As with many very hardy weeds, Wireweed can be used in cases minor cuts and scrapes to staunch the bleeding. Like most of its hardy cousins who live on waste ground, it is full of tannins that bind proteins in wounds and help clotting. Taken as a tea, it can also help haemorrhoids and diarrhoea as its tannins and flavonoids bind and sooth the membranes of the gut and intestines.

It has another benefit that might not be so obvious, it contains powerful decongestant compounds making it helpful in cases of coughs and cold.It helps soothe inflamed mucous membranes in the mouth and throat
